Description of key information
Cyclabute NOEC for micro-organisms is >=1000 mg/l based on read across from Cyclobutanate which was tested in an OECD TG 209 test.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 1 000 mg/L
Additional information
The executive summary of the Cyclobutanate test on micro-organism is presented below. The read across justification is presented in the Aquatic toxicity Endpoint summary.
Cyclobutanate effects on micro-organisms
The effect of Cyclobutanate on the respiration rate of activated sewage sludge was investigated in a test according to OECD Guideline 209 under GLP. Validity criteria for the test were met. The effect of the test material on the respiration of activated sewage sludge gave a 3-hour EC50 of greater than 1000 mg/l. The No Observed Effect Concentration (NOEC) after 3 hours exposure was >=1000 mg/l.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
